John Dalton

John Dalton was born in September 5,1766 in Eaglesfield in Cumberland, England. Dalton and his family lived in a small country house. His family had been Quakers since 1690. Quakers where members of a society of friends. John had a brother named Mary and A brother named Charles, when he was born his brother was twelve years old and his sister was two years old. Dalton's birth was not recorded, so when he grew up older he asked one of his relatives and got and answer which was his birthday. His parents were honest people and good workers. His dad Joseph had land he had inherited were Dalton and his brother Charles help out with the crop. His mother Deborah Greenup homespun textile Dalton's sister help her too. John Dalton's family were poor but "although they were never hungry they were poor" Dalton was lucky he was a Quaker , other boys received little or no education, but as Quakers Dalton received a fair education at the closest Quaker school . For Dalton it was an achievement going to school since in those times only one out of two-hundred and fifteen people could read. John Dalton went to the Quaker school at Pardshow Hall. Dalton was quick when it came to studies and in mathematical problems he was good and seem to be tireless of them. John Fletcher was Dalton's teacher, he was a smart man who didn't use a rod to hammer in learning to Dalton, he was to provide Dalton with a excellent back-round and lifelong quest for knowledge. Then came Elihu Robinson a rich Quaker gentlemen. who become Dalton's mentor, and was another person to lead Dalton to mathematics , science, and specially meteorology. John Dalton had an intense fascination for meteorology he even in fact kept careful daily weather records for forty six straight years. When Dalton was twelve he opened his school in Eaglesfield. He was smaller than some boys so he was threatened by the older boys who wanted to fight with the young teacher. He managed to control the kids for two years, but eventually...

...Synopsis
Chemist JohnDalton was born September 6, 1766, in Eaglesfield, England. During his early career, he identified the hereditary nature of red-green color blindness. In 1803 he revealed the concept of Dalton’s Law of Partial Pressures. Also in the 1800s, he was the first scientist to explain the behavior of atoms in terms of the measurement of weight. Dalton died July 26, 1844 in Manchester, England.

Early Life and Career
British chemist JohnDalton was born in Eaglesfield, England, on September 6, 1766, to a Quaker family. He had two surviving siblings. Both he and his brother were born color-blind. Dalton's father earned a modest income as a handloom weaver. As a child, Dalton longed for a formal education, but his family was very poor. It was clear that he would need to help out with the family finances from a young age.
After attending a Quaker school in his village in Cumberland, when Dalton was just 12 years old he started teaching there. When he was 14, he spent a year working as a farmhand, but decided to return to teaching--this time as an assistant at a Quaker boarding school in Kendal. Within four years, the shy young man was made principal of the school. He remained there until 1793, at which time he became a math and...

...JohnDalton and Atomic Theory
JohnDalton was a British scientist who made important contributions to science and to the atomic model specifically.
I. Experiences in his life that led to his interest in science and the study of the atom
A. Education and teaching career brought him in contact with amateur meteorologists
B. Mentors and meteorology directed his interest toward air pressure and properties of gaseous elements
C. Study of elements led to interest in components of elements and his atomic theory.
D. This is the general path to his discoveries. However, no one knows specifically how he reached most of his conclusions about atoms.
II. Work on the atom and its contribution to the modern atomic model
A. Lavoisier’s Law influenced Dalton’s assertion that atoms cannot be created, destroyed, or subdivided.
B. Proust’s Law of Definite Proportions led Dalton to his Law of Multiple Proportions
C. He was trying to explain why water absorbs different gases in different proportions.
D. Contributions
1. All matter consists of tiny particles, atoms.
2. Atoms cannot be created, destroyed, separated into smaller parts or transformed into another element.
3. All atoms of the same element have identical weights, while atoms of different elements have different weights.
4. When elements react, their atoms combine in simple, whole-number ratios....

...JohnDalton was a born September 6, 1766 in Eagelsfield, Cumbria in England, but spent most of his life in Manchester. He was a British Chemist and physicist. He
was the son of Weaver and he received his early education from his father. At the age of 12 Dalton began teaching at Quacker School in his native town. In 1781 he moved
to Kendal, where he conducted a school with his cousin and his elder brother. He then went to Manchester in 1793 and spent the rest of his life in Manchester as a teacher, first at New College, and later as a private tutor. Dalton suffered a minor stroke in 1837, and a second one in 1838 left him with a speech impediment, though he remained able to do experiments. In May 1844 he had yet another stroke; on 26 July he recorded with trembling hand his last meteorological observation. On 27 July, in Manchester, Dalton fell from his bed and was found lifeless by his attendant. Approximately 40,000 people filed by his coffin as it was laid in state in the Manchester Town Hall. He was buried in Manchester in Ardwick cemetery. The cemetery is now a playing field, but pictures of the original grave are in published materials. Dalton was a life long bachelor.

(September 6, 1766–July 27, 1844)
November 14, 2012
JohnDalton was born on September 6, 1766 in Eaglesfield, Cumberland to Joseph Dalton and Deborah Greenup. He grew up with an older brother named Jonathan and a younger sister named Mary. He was educated by his father and John Fletcher (a teacher at Quaker school), and started teaching himself after Mr. Fletcher had retired in 1778. Dalton was however unsuccessful and began farm work after two years. In 1781, he left the farm to become an assistant to his cousin George Bewley in Kendal. He spent twelve years there and in 1790, thought about studying law or medicine but since his family did not encourage him to do so, he remained a teacher until the spring of 1793, where he moved to Manchester. Here he was appointed teacher of math and natural philosophy at what is now known as Manchester College, Oxford until 1799 where he became a math and chemistry teacher.
After Dalton’s death, Dr. Thomson discovered the electron. He continued studying the atomic theory to come up with an improved atomic theory and “The Raisin Bun Theory.” Thomson’s atomic theory was that “matter is composed of atoms that contain electrons (negative particles) embedded in a positive material. The kind of element is characterized by the number of electrons in the atom.” Dalton is known as the one who developed the...

Five main points of Dalton's atomic theory
1. Elements are made of extremely small particles called atoms.
2. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties.
3. Atoms cannot be subdivided, created, or destroyed.
4. Atoms of different elements combine in simple whole-number ratios to form chemical compounds.
5. In chemical reactions, atoms are combined, separated, or rearranged.
Dalton proposed an additional "rule of greatest simplicity" that created controversy, since it could not be independently confirmed.
When atoms combine in only one ratio, ".it must be presumed to be a binary one, unless some cause appear to the contrary"..
Dalton proceeded to print his first published table of relative atomic weights. Six elements appear in this table, namely hydrogen, oxygen, nitrogen, carbon, sulfur, and phosphorus, with the atom of hydrogen conventionally assumed to weigh 1. He hypothesized the structure of compounds can be represented in whole number ratios. So, one atom of element X combining with one atom of element Y is a binary compound. Furthermore, one atom of element X combining with two elements of Y or vice versa, is a ternary compound. Many of the first compounds listed in the New System of Chemical Philosophy correspond to modern views, although many others do not.
Despite the...

JohnDalton is best known for his pioneering work in the development of modern atomic theory, and his research into color blindness. He devoted his life to teaching, research, and practicing his faith. He will be deeply missed by his friends and family. His parents were Deborah Greenup and Joseph Dalton. He had an older brother that was seven years older then him and older sister that was 2 years older then him. He had a long, happy successful life with Physics and chemistry, and he will be missed.

...John Locke – The Second Treatise of Civil Government
John Locke
* Widely known as the Father of Classical Liberalism
* Was an English philosopher and physician regarded as one of the most influential of Enlightenment thinkers
* His work had a great impact upon the development of epistemology and political philosophy.
* Considered one of the first of the British empiricists. he is equally important to social contract theory.
* Published the “Two treatises of Government” in 1689
Two treatises of Government
* Two Treatises is divided into the First Treatise and the Second Treatise.
* The First Treatise is focused on the refutation of Sir Robert Filmer, in particular his Patriarcha, which argued that civil society was founded on a divinely sanctioned patriarchalism. Locke proceeds through Filmer's arguments, contesting his proofs from Scripture and ridiculing them as senseless, until concluding that no government can be justified by an appeal to the divine right of kings.
* The Second Treatise outlines a theory of civil society. John Locke begins by describing the state of nature, a picture much more stable than Thomas Hobbes' state of "war of every man against every man," and argues that all men are created equal in the state of nature by God. From this, he goes on to explain the hypothetical rise of property and civilization, in the process explaining that the only legitimate governments are those...

...A crucible is defined as a severe trial or a container in which metals are melted at very high temperatures. Much like how metals mold to a new shape at very high temperatures, people change when severe trials and challenges present themselves. When innocent lives are lost, a person will realize the wrongs and attempt to make things right again. The character John Hale must forget his old teachings and way of life to try to return the town of Salem to a peaceful community. In Arthur Miller’s The Crucible, Reverend John hale transforms from a prideful prosecutor of witches to a humble defender of the accused because of the guilt he experiences over the innocent lives lost during the Salem witch trials.
Reverend John Hale arrives in Salem as a prideful man with intentions of persecuting the accused of witchcraft and ridding the town of all evil. Author Arthur Miller says of Hale, “This is a beloved errand of him; on being called here to ascertain witchcraft he felt the pride of the specialist whose unique knowledge has at last been publicly called for.”(Miller 1252) Miller explains that the reverend has great pride in having the opportunity to show off his skills to rid the town of Salem of witchcraft. His skills in the beginning of the trials come from his books instead of from his own intuitions. Reverend Hale brings many books into the town in order to use their knowledge to persecute the accused. He believes these books to be...
